PLASTER TERMINAL.

Application filed September 12, 1927. Serial No. 219,093.

My invention relates to plaster terminals and particularly to a novelone-piece sheet metal terminal.

It is well known that plaster terminals of all kinds and types have beenpresented to builders, with more or less success. One of the greatestdificulties in the past has been to produce a plaster terminal that willfit snugly over a rough buck, insure rigidity, and accurate alignment.

The device or my invention is intended to overcome all the defectspreviously encountered in a device of this type. My invention consistsof a single piece of sheet metal having a plurality of cars contactingone side of the rough buck, and the other angle contacting the otherface of the rough buck. The metal is bent at right angles to the basemember and terminates in a backwardly disposed bead that functions notonly as a plaster terminal, but also as an anchor for the adjacentplaster.

The device will be more readily understood by reference to theaccompanying drawing, in which;

Fig. 1 illustrates a perspective view of a device constructed inaccordance with my invention.

Fig. 2 is a similar view of a modified con struction showing the earscut through the full width.

In the drawing, and referring particularly to Fig. 1, it will be seenthat I have illustrated a rough buck, A, door jamb and stop, B, andplaster C. The usual plaster support or lath is not shown. The device ofmy invention consists in a long, relatively narrow strip of: metalhaving a base 10, plaster defininn" portion, 11 and plaster bead 12.Formed out of the metal in said base, are the cars 13 which are bent atright angles to the plane of the base 10, on the line 14 at intervalsalong the length of the strip. The plaster defining portion 11. isformed at right angles to the base 10 on the line 14, and terminates ina longitudinal bead 12 which is bent back on itself to form less than aright angle with the plaster defining portion. This bead serves tostrengthen the edge against possible bending by being struck by objectsduring con struction, as well as to provide a secure anchor for theplaster which fills in behind it. The base 10 and the ears 13 areintended to contact the narrow and the wide faces respectively, of arough buck and to insure a firm and rigid contact for the plasterterminal. The cars and the base may be provided with apertures 15 toreceive nails or other securing means.

In installation, the device is set up around the corner of the roughbuck and securely nailed in place. The finishing members, such as thedoor jamb and stop, may then be applied. Plaster C may then be appliedover the lath or screen (not shown) the thickness of the plaster beingdefined by the portion 11.

In Fig". 2 I have shown a slightly modified form of my invention, theonly diilerence in the two being that the cars 16, 17 are longer and arecut through to the edge of the base. By this modified device, a morecertain and more rigid Contact is had with the rough buck and. thepossibility of injury from a blow directly on the face of the portion 11(Fig. 1) is much reduced Of the two forms here illustrated. the formindicated in Fig. 2 is con sidered the more preferable, being strongerand more easily handled, the cars 13 shown in Fin. 1 being of such smallsize as to be capable of easy destruction by contact in shipping andhandling.

The provision of the cut-away portions 16, 17, enables the insertion ofwedges between the buck and the jamb without interference with the metalportion of the terminal. By placing the wedges at points between theportions 17, they may be positioned in the same manner as though theplaster terminal had no part projecting into that space.

Thus it will be seen that my invention provides a plaster terminal thatis simply made, easily handled, easily installed by unskilled workmen,and highly ehlcient. The strips can be furnished in any desired lengthor cut to any convenient size without destroying the efliciency thereof.

Obviously modifications and variations may be made in the design andconstruction here illustrated, and I do not wish to be limllll) itedexcept as indicated in the appended claim.

I claim:

A device of the class described consisting of a strip of metal having arebent outer margin constituting a plaster anchor or bead, the inneredge being slitted at intervals, alternate sections of the slitted edgebeing bent at right angles, the series of angularly disposed sectionsbeing adapted to lie alongside of and be secured to a wood frame member,the portion of the strip between the bent sections and the beadconstituting a plaster defining terminal.

In testimony whereof I have affixed. my signature.
